Of course, that's good: they wouldn't ask you to share a bed if they suspected anything, right?
But being so close to your step-mother? It's impossible not to want her again. She tells you it's not going to happen but you know that she'll change her mind when she sees how hard you are for her. She gets so cock hungry when she sees how hard she makes you. She grasps you through the blanket, squeezing your dick and smirking.
She shushes you, anxious but clearly horny, as she pulls the blanket off and exposes your dick, hanging out of your boxers and ready for her talented hand.
As much as you've been flirting and fooling around, the most you've done is have her jerk you off onto her body. Every time you push for more, she shuts you down. Tonight, with your cock against her pussy, she jerks you a little closer to the wet opening.
You can tell she wants it, too, but when you press forward, she insists that you can't. "They could wake up any minute!" she says, but she doesn't move away. You keep pressing, running your cock against her clit to make her even more wet, more unable to say no. Finally, she leans back, and tells you it's time.
"But just the head, ok?"
You watch her face contort in ecstasy as you push the fat head of your cock into your step-mother, for the very first time. She puts her hand over her mouth to stifle the uncontrollable moans you've elicited from her. You try to obey her rules, but the both of you are so turned on, you start to push more and more, slowly working your cock into her, being careful not to make too much noise.
After a while of this slow fucking, of these tender, careful, thrusts into your step-mothers dripping pussy, she tells you she wants you all the way in before you - can you have heard this right? - before you cum. Yes, she said she wants you to cum inside her! Deep, deep inside her. You watch as she works herself all the way down your thick member, burying you deep inside her, whispering for you to cum inside her. It takes everything in you not to groan, to cry out for her, as you let go of a huge, powerful load inside her!
